Also in the cluster monitor we are getting status change from[1]. AFAIU
that process logic is not execute ever and stateChanged will be always
false.Is n't?
// Checking the current status of the cluster instance
boolean stateChanged =
ServiceReferenceHolder.getInstance().getClusterStatusProcessorChain()
.process("", cluster.getClusterId(),
clusterInstance.getInstanceId());
AFAIU we have to listen to all the cluster events[2] for decide the current
status of the cluster.
